The instantaneous slew rate of the transmitter
output is internally limited to a maximum of 30V/
μ
s in order to meet the standards [EIA RS-232-D
2.1.7, Paragraph (5)]. However, the transition re-
gion slew rate of these enhanced products is typi-
cally 10V/
μ
s. The smooth transition of the loaded
output from V
to V
clearly meets the mono-
tonicity requirements of the standard [EIA
RS-232-D 2.1.7, Paragraphs (1) & (2)].
Receivers
The receivers convert RS-232 input signals to
inverted TTL signals. Since the input is usually
from a transmission line, where long cable lengths
and system interference can degrade the signal, the
inputs have a typical hysteresis margin of 500mV.
This ensures that the receiver is virtually immune
to noisy transmission lines.
The input thresholds are 0.8V minimum and 2.4V
maximum, again well within the
±
3V RS-232
requirements. The receiver inputs are also pro-
tected against voltages up to
±
15V. Should an
input be left unconnected, a 5KOhm pulldown
resistor to ground will commit the output of the
receiver to a high state.
